Therefore, it can be easily lifted by one person, and it is safe even when piled up at a high place, and does not require mechanical force such as a crane.

(2) The first multi-layer wall material or the second multi-layer wall material is fitted in the fitting parts or in the fitting parts in the vertical and horizontal directions through the coupling holes.
Furthermore, since it is a multi-layered wall girder structure that is engaged with and fixed to the intersecting wall that is deeply overlapped vertically by the engaging portion and the locking portion,
It is possible to construct a structurally stable structure against external force without using dowels or through bolts.

(3) Since the structure to be constructed is an integral structure of multi-layered walls composed of inner and outer walls, external force can be dispersed and received, so that the wall need not be thicker than necessary. It can be made solid, there is no waste of material, and resource saving can be achieved.

(4) Since the outer wall and the inner wall of the first multilayer wall material or the second multilayer wall material face each other and closely adhere to each other, like a conventional girder structure such as a log house. ,
There is no need to caulk and fill the gaps between the upper and lower material joining surfaces, to provide engaging grooves for close contact, or to actually process unevenness.

(5) By simply changing the width of the groove of the basic material, a double-walled, triple-layered, quadruple-layered, multi-layered wall cross-structured structure can be produced. It is possible to make various structures that meet the conditions.

(6) If a standardized material such as 2 × 4 material is used, the labor required for processing is only the groove at the wall intersection, and the basic material is a square having the same wall length on each side. , It can be the same shape, and if it is rectangular, the facing walls will be the same shape, easy to process and assemble, good workability, no skill or experience is required for assembly, anyone can assemble be able to.

(7) It is not necessary to use thick logs or timber,
Since it is possible to use a plate material that is weak in strength and is not suitable as a structural material until now, or a 2 × 4 material that is widely distributed in the market, it is possible to construct a structure inexpensively and inexpensively.

(8) Since nails, bolts, dowels, etc. are not required for assembling the wall, it is easy to disassemble and reassemble.

(9) The basic material is not limited to wood, and various materials such as plastic, ceramic, metal, cement board, wood board and cardboard can be used as long as they satisfy the required strength. If the basic materials of these materials with different properties are combined over part or all of the multi-layer wall to form a multi-layer wall material composed of composite materials to construct the wall surface, the performance of the cross girder structure of the multi-layer wall is improved. By using a basic material made of a material having excellent heat insulating properties for the intermediate layer between the outer wall and the inner wall of the multi-layer wall material, it is possible to produce a multi-walled cross girder structure having excellent heat insulating properties.

(10) The outer wall layer is made of a fire-resistant material as a basic material, and the inner wall layer is made of wood as a basic material to form a multi-layer wall, and the wood portion of the inner wall layer protruding from the outer wall is made to be fire resistant. When covered with the material, the fireproof performance can be improved without impairing the habitability on the indoor side.

(11) By utilizing the multi-layer wall as described above, it is possible to improve waterproofness, immortality, weather resistance and the like by using the same method while maintaining the integral structure of the wall surface. .

(12) Using the wall construction method according to the present invention, a box of a square or polygonal double-sided girder whose wall surface is composed of multi-layer wall material is prepared, and a bottom plate having an appropriate shape is fixed or a bottom plate is fixed. A starter or a base composed of a starter and a basic material is fixed on the top, and from this the starting material is used to assemble a box of a multi-layered wall girder set with the basic material, a lid is provided if necessary, and a box, container, We can make storage cases, containers, packages, etc.

[0049]

In summary, according to the present invention, the wall crossing portion is fixed by the grooves by locking the basic materials vertically and horizontally, and further, the plurality of basic materials fitted in the grooves are stronger by friction. Since the outer walls and the inner walls composed of the multi-layer wall materials are combined and stacked in a state where they are offset from each other, each basic material is strong and stable even if it is a light and thin plate-like body. Further, it is possible to construct a double girder structure having excellent airtightness.
